Head to the pool for a break.
At times, the trip might feel more like babysitting depending on the age of your young ones. When you reach this point, head to the pool for some much-needed (and deserved) relaxation time. Your grandkids can continue burning their seemingly endless supply of energy while you bask in the sunlight and enjoy a light snack or early drink. If you hit the pool during a busy time, there should be enough kids around the same age to give your grandkids people to play with. Once you've regained your energy, you can hop in the pool too for a game of Marco Polo or a splashing battle.
